Alyson Hannigan reveals 'American Reunion' details

The How I Met Your Mother actress, who plays Michelle in the comedy series, disclosed that her character now has a child with Jason Biggs's Jim Levenstein.

"We're still married, and we have a child. So we're navigating the waters of parenthood and how that changes the dynamics of a relationship," she told Entertainment Weekly.

"But also they're going back to their high school reunion and so there's some nostalgia there of, 'Aw, remember what we were like when we first met?' That kind of stuff. It's really nice. I really love that relationship and they've stayed true to it.

"The great thing about this franchise is that, of course, there's the raunchy humor but there's also a lot of heart to it. And this fourth movie does not miss the boat on that at all."

Asked if Michelle will be showing her "flute-playing prowess" in the sequel, Hannigan added: "There will be some... Uh... Yes, you know, it's a reunion. What's great about what [screenwriters Jon Hurwitz, Hayden Schlossberg] have done is they've made a really good movie that people who aren't familiar with the franchise will love, but they've also given the people that love the franchise a lot of inside jokes and stuff that you'll really appreciate if you're a fan of the American Pies."

Seann William Scott, Tara Reid, Mena Suvari, Shannon Elizabeth and Chris Klein will reprise their roles in American Reunion, which opens in cinemas in April 2012.
